Brake Light problems of the 2014 Tesla Model S

See NHTSA action # 20010. Media control unit failed 7/8/2020 @ 5:04 pm when returning to the car after a brief stop, in a parking lot. Car took several minutes to "reboot" to drivability, but center screen is still down. Backup camera and blinkers (inside or outside, confirmed) are not working. Additional items down include defrosters, auto tilt mirrors for reversing, seat heaters are stuck on (from when I had last used them), sunroof won't open (it ignores steering wheel controls). Brake lights are still functional, so I drove it home. Called Tesla and was told that the replacement module is out of stock and is not expected for many weeks. In the meantime, the car is undrivable.
